No, unfortunately. Sheer Force only removes positive secondary effects, like a chance to burn, chance to raise your stats, or a chance to lower the opponent's stats.
"Sheer Force does not negate primary effects such as recoil, stat penalty or status condition for the user, increased critical hit rate, moves that never miss, moves that change power, two-turn moves, etc."
Hope I helped! :)
P.S. If you use the ability Iron Fist, Focus Punch gets a boost, though.
